l SMOKING PIPE Filed sept. 2, 19321 I #2 y1/2 d@ a@ Patented Feb. 25, 1941 UNITED STATES PATENT orf-ICE 13 Claims.

This invention relates to smoking pipes, and among other objects, is intended to provide a no-vel construction and arrangement whereby a cool, dry smoke may be obtained.

Another object of the invention is to provide novel means whereby ,air may be mixed with the smoke after leaving the bowl and before being taken from the discharge e'nd of the stem.

4Another object of the invention is to provide automatically actuated means for controlling the admission of air to the smoke duct between the pipe bowl and the discharge end of the stern.

Another object of the invention is to provide a novel .arrangement whereby the automatically actuated means for controlling the admission of air to the smoke duct may be rendered ineffective for that purpose, if so desired, and at the will of the user.

Another object of the invention is to provide thermostatically actuated means for automatically controlling the ,admission of air to the smoke duct.

Another object of the invention is to provide a novel construction and arrangement wherein the thermostatically actuated means for controly ling the admission of air to the smoke duct is effected directly by the temperature of the smoke Within the duct, and is fully'protected against the inuence of any variation in atmospheric temperature outside the smoke duct.

A further object of the invention is to provide an .air cooled pipe having suitable moisture retaining means therein.

A still further object of the invention is to improve devices of the character described in sundry details hereinafter referred to and particularly pointed out in the appended claims.

One embodiment of the present invention is shown for illustrative purposes in the accompanying drawing in which:

Fig. 1 is an enlarged elevational View, partly in section, of a smoking pipe embodying features of the present invention;

Fig. 2 is a fragmentary perspective View of a 'portion of the structure illustrated in Fig. 1;

Fig. 3 is a further enlarged transverse sectional View taken substantially as indicated by the line 3-3 of Fig. 1;

Fig, 4 is :an enlarged transverse sectional View illustrating a portion of the structure shown in Fig. l, and taken substantially as indicated by the line 4-4 thereof; and

Fig.A 5 is a transverse sectional view similar to Fig. 3 showing certain of the parts in relatively changed position, and illustrating the manner of rendering the automatically actuated means ineffective to admit air to the smoke duct.

This invention is, in part, an improvement on the smoking pipe of my co-pending application, Serial No. 118,238, led December 30, 1936, and in the illustrative embodiment shown in the drawing, the present invention comprises a bowl 8 having a stem associated therewith .and indicated, as a whole by the numeral 9, the said stem being shown, in the present instance, as comprising a portion II formed integrally with the bowl 8 and having a smoke duct or chamber I2 formed therein .adapted to communicate at one of its ends through a passage I3 with the interior of the bowl 8, and provided at its opposite end with an open end portion adapted to receive a mouth piece indicated, asa whole, by the numeral Hl shown, in the present instance, as comprising the outer or discharge end portion I5 andan inwardly extending portion I6 of reduced diameter adapted to be positioned within the open end portion of the stem II with a degree of snugness capable of retaining the mouth piece I4 against accidental displacement with respect to the stem II, but free to be rotated manually with respect thereto if so desired, the mouth piece I4 including also an elongated extension or finger Il extending intothe chamber I 2, preferably, in spaced relation to the walls thereof, and shown, in the present instance, as a tubular member positioned substantially in line with and forming an extension of an elongated passage I8 formed in the mouth piece.

The linger Il is shown, in the present structure, as provided on one side thereof with a cutaway portion Aforming an elongated opening I9 through which smoke from the chamber I2 may enter the passage I8 of the mouth piece, and is provided, preferably, `at its opposite side portion with a plurality of apertures 2l through Which moisture may drain or escape from the member Il into the `chamber I2 where it may be retained, thereby providing a dry smoke for the user free from condensate or other moisture.

For admitting air to the chamber I2 for cooling purposes, the stem II, preferably, adjacent the open end portion thereof is provided with .an intake port o-r opening 22, and for automatically controlling the admission of air through the port 22, a thermostatic element 23 shown, in the present instance, as of the well known laminated type, consisting of two layers of different metals having relatively different co-eicients of eX- pansion, is positioned, preferably adjacent the cut-away portion or elongated opening I9 of the finger I'I, and is secured adjacent one of its end portions, preferably, to the inner end portion of the finger I1, as indicated at 24, and provided adjacent its opposite end with a valve portion 25 extending into a recess 26 formed in the portion I6 of the mouth piece I4, and adapted, normally, to cover the intake port 22, as clearly illustrated in Figs. 1 and 3, in a manner to prevent the admission of air therethrough.

It will be apparent, however, that by reason of the arrangement shown and described, when the heat of the smoke in the chamber I2 is suflicient to actuate the thermostat 23, the valve portion admission of air to the smoke duct or chamber I2 is controlled directly by and in proportion to the temperature of the smoke within the duct ,as it passes to the mouth piece of the pipe, and that by positioning the thermostat within the smoke duct, thethermostat is fully protected against the influence of outside atmospheric temperature conditions, thereby providing ample assurance of the continued efficient operation of the thermostat for controlling the passage of air intothe chamber I2 in accordance with the temperature of the smoke therein.

As previously mentioned, the mouth piece I4 and elements mounted thereon may be manually rotated within the stem Il, and by reference to Fig. 5, it will be noted that by rotating the mouth piece, preferably, through an arc of 180, the end portion 25 'of the thermostat will be removed from adjacent the inlet port 22, thereby rendering the thermostat ineffective to admit air to the chamber I2, in which event, a pipe embodying features of the present invention, may, if desired, be used as an ordinary pipe. Thus, it will be observed that by such an arrangement, the admission of air through the port 23 may be manually, as well as automatically, controlled.

It will be observed from the foregoing description that the present invention provides a novel construction and arrangement whereby air may be admitted to the smoke ducts or passages for cooling the smoke before reaching the mouth of the user, and wherein the admission of air is automatically controlled by thermostatically actuated means, which, if desired, may be rendered inoperative at the will of the user; also, that the present invention provides a construction and arrangement whereby moisture may be removed from the smoke passages before entering the mouth piece, thereby providing a cool, dry smoke.

Obviously, the present invention is not limited to the precise construction and arrangement shown and described as the same may be variously modified. Moreover, all the features of the invention need not be used conjointly as the same may be used to advantage in variously diierent combinations and sub-combinations.
